The singer-actress rocked a “Sustainability is Sexy” shirt.

Dove Cameron, whose TV movie “Descendants 3” recently premiered on Disney Channel, is also part of a summer theatrical sequel.

The singer-actress voices Ella in “The Angry Birds Movie 2,” which opens on Tuesday, August 13.

Ahead of the opening, Dove attended an official premiere in Los Angeles.

In addition to supporting the movie, she advocated for sustainability with a “Sustainability Is Sexy” T-shirt. The outfit may not have made for traditional red carpet glam, but insofar as she looked great and delivered an important message, the look was certainly a win.
